' form and arrangement f of 'starting andV Presses,l of which the following is a speciiication, reference being had to the accompanyingdrawings. A

My invention relates to printing presses and it has for one of its objects to provide new andY improved meansv automatically effective upon the breaking of VVthe webV of paper being rprintedvgto -throfwfthe press out of operation relativeto-the driving means. Itis another object of my invention to.pro vide, -in a press comprising a plurality .of printing couples aetin'gupon separate'webs, means for driving 4the several printing couples independently lof the .remainder "of, the press, so that when a single .web breaks the proper one of the printing couples may be driven independently .for rethreading the broken web whereby there may be a minimum wast-age of paper as a result of the form and arrangement of means forf'throwf ing-the press'into slow'fspeed operation and then'y into high speed operation at theL desired moment. Itis another object of my invention to provide` a new :and-improved stoppingk means for the press ,comprising a suitable brake` adapted to act upon the press independently olf-the driving motor. It is another object of my inventionto improve presses of this type yinsundry details heref inafter pointed out.V The preferred means by which I have accomplished my vseveral are hereinafter specifically described. AThat which I believe to be newand desire to cover by this application kis set forth in the claims. In thedrawings: 1 Figure l,l is a. view Vofia part ofa press f' embodying my improvements;-`

V Referring to drawings in which corresponding parts are indicated by the same reference characters,- y j A 10 indicates the framework of a ypress comprising longitudinally-extending frame bars 11and12, and atransversely-extending frame bar 13. Two sets of printing mechanisms are-shown in the drawings, one set comprising impression ycylinders'lil-15 and form cylinders 16e-17, landthe ,otherI set comprising impression Vcylinders 15E-+19 and form cylinders 20-.21. Asis indicated by the showing of Figf, each of the im-A the several figures ofl the i l pression cylinders and form cylinders is prol vided with a suitable-driving gea'rQQy at one end, the several gears 22 of eachset of printing devices being in'mesh in series with each other and with gears 23 and 24C so as to be properly driven,- the gears 24 being fixed upon shafts 125'-26, i respectively, suitably mounted `onl the framework -10.. Any suitable typeof inking Kmechanism is adapted to beused, kand inasmuch as such inking mechanism lforms no partof thefpresent inventrate or describe it.y g e Means is provided for rotatingtheshafts 25-26 at variable speeds eitherseparately tion it is not believedlto be necessary to illus- Vor in unison.`vv Thismeansfcomprises bevel gears ,Q7-#28 vmounted -upon the. shafts E25-26, respectively,: meshing v.with bevel gears 2930 revolubly mounted upon a vertical shaft 31.` l The gear-2l9 has iXedly connested, with it a gear 32? andra clin-,eh,inemM ber 33 which is adapted to be driven by a coperating clutch member 34 mounted upon the shaft 3'1 solas to rotate therewith but so as to be-slidable longitudinally thereof into engagement with the clutch member 33 or out. of engagement Itherewith against the action of 'a spring 35. Therbev'el gear 30 Vhas rigidly connected with it a gear 36 and a clutch member 37, which is adapted to be driven by a coperating clutch member 38 which is Amountedupon the shaft 31 so as to rotate therewith but so as to be movable longitudinally thereof into'engagement with the clutch member 37 or out of engage nient therewith4 against the action'of a spring39;l With theclutch members 344-38 in operative engagement with 'the coperating clutch members 33 37, andV with shaft 31 being drivenV clockwise direntio'r'i in Fig. 2', the printing couples are adapted ab@ 'antenas a dire-Caen for eem-yingthe which meshes with a gearV 49 V.fixed upon a sleeve 50 revolubly mounted upon a'shaft 5,1, which, inthe construction shown, is in alinement Vwith the shaft43. Fixed upon the sleeve 50 (see F ig; '4) is aoratehet wheel 52 which adapted thriigh the nfiediumef three'pawls 53 to drive a drum-54 in jclockwise `direction iii said Fig.' 4; The drum54 isY adapted i.te be cnnected by vmeans of a clutch mechanisrn4 55 of 'any *suitable type n with theehaft 51 for causing'the drum andl the -shaft to rotate together, theV clutch` mechanism 55, in thegconstruction shown, comprising levers 56 which are adapted to be aspread' apart for clutc'hing the drum 54 v to the shaft 51 by` movementof a head y57 longitudinally ofthe yshaft 51 t'oivard the drum, as hereniafte'r'v described. Motion is 4 tr'ansmitted from the shaft' 51 to the shaft 4 7 by means of a ypinion 58 fixed Vupon the Y'shaft 51 andineshing with a gear 59 fixed Y uponl the shaft 47. 'Motion is ytransmitted 'from theshaft 4 7 teA the shaft e1-by 'means of -intermeshing bevel gears 604-61; By reason ofthe 'rela-tive sizes of .the1 interniesh# n ing gears 44,-45, 48-49, andL v53;59, the shaft 31-is"'drive`n ata comparatively very ,slowyspeed as compared to' that 'of'the motor l42, being designed tobe-'dri'venat a speed ofl ten totwenty revolutions per minel 'las es tempered@ 50091321 1000 revolutions' 45ai'retiywiterthe 'Shaft 47 whenever dei S. "fr 'vded -f'r lconnectingv the gear sired, such means comprising a clutch mechanism 62 comprising arms or levers 63 adapted to be vspread'apart by a longitudinal movement of a head 64 slidably mounted upon the shaft 47 for connecting the clutch member' 62 'with the shaft. With the shaft 47. being drivenat low speed by the gear 45 throughthe mediumv of the gears 48 and'yv49, the clutch 55, the shaft 51 and the gearsv 58-59, the clutch 62 may be thrown vinto operation by a longitudinal movement of the head 64 causing the shaft 47 to rotate at comparatively high speed with the gear 45 and the clutch mechanism 62. This actioni'serves *to rotate the shaft 51 at a comparatively very high speed relative to .the speed of the gearv 49, the pawls 53 being adapted to slip Vover th'e` teeth of the `ratchet 52 for this purpose.. With the clutchmember '55 rotating at high speed with the shaft'51, the pawls 53 are adapted to be thrown by centrifugalffor'ce 4out of mesh with the teeth of the ratchet wheel 52, making it unnecessaryl to thro'wthe clutch 55out of'operation.

' `Means is provided for 'moving the heads 57-64 ieiigaudiany er the 'shafts 51417 respectively for throwing the clutchV mem`V v bers 55 and 62 into'and outV of operation in proper timed relatien to eachother, The head 57 is adapted tofbe'moved longitudinally by means of a yoke 65 engaging a suitable circumferential groove in the head 57, said yol'e-being vpivotally mounted upon a bracketl 66 extending laterally from the frame barY 11. The yoke 65 is operated by 'an arm 67 provided with -a roller v68 at its upper end working in a siiitable vcam groove in a cam member 69 fixed'lupon a shaft -70 extendingtransversely of thepr'e'ss. y r1he head -6'4 is ,Q adapted tobe moved` longitudinally thniughV the medium of-a 'yeke 71 the lower' ends of `which, engage-a suitable groove inY the said head'64. *The yoke 7l is 'pivotally mounted up'on 'a bracket 72 extending transver'sely fromv the frame bar1-2 (see Fig. 3). The yoke 71 is 'operated by an arm 73 pro; vided its upper end withY a roller v74 engaging'a suitablecam groove cam member 75 also fixed upon the shaft 70.' As wil-l be seen from 'an inspectionof 2 and3, when the 'shaft 70 isgiven approximately aquart'e'r of la reveluti'on in 'counter clock? wise direction in Fig.vv 1 from the" position shown in Fig. 2,"thefcliitch member 64y is not affected by reason of theY dive'llv inthe cam groove in kthe ca'mmember75, but vsuch rotation of thev shaft 70 serves to throw the clutch 57 into operation, serving to'drive at Y low speed. Upon the next-succeeding quarterrevolution of the Vshaft 70 lin the same direction, the' cl`uteh64 isthrowninto operation, serving to 'drive-.the shaft 47' at'high speed.

"is provided with a switclr first thrown outk of operation, and indue time the low speed clutch 55 is thrown out of operation, bringingthe apparatus to the condition shown in Fig. 2. Upon a still further. rotation'ofthesh'aft 70 in clock-y wise direction in Fig. l, a brake-band 76 is tightened about a brake-drum 77 vmounted upon theshaft y5l, this effect. being attained through the medium of a lever 7 8v and a link 79 having anpeccentric connection at its upper end'with the shaft 70. By means of thisbrake the press-is gradually slowed down and stopped independently ofk the r0- tation of the heavy'motor 42.

The motorBO is preferably4 pro,-y vided with cont-rollervv means by which` the motor is` automatically thrown, out of operation when the shaft has been given a quarter turn for-throwing .the clutch mechl anism 57 intok operation. When theipress has been driven at a `slow speed for the de# sired period of time, and the motor jSO has been again thrown into operation for rotating the shaft 70 still further forthrowing theclutch mechanism62 into operation, the controller means preferably serves to throw the motorli'SO .out of operation promptly after the clutch 62 lhas been thrown into operation. .When the" motor 8() has been set into operation for turning the shaft 7 0 in a directionfor throwing the clutch mechanisms 62V and 55 out of Loperation, the controller system preferably serves to maintain the motorSO in operation until after both clutcheshave been thrown out and the brake has been set7 whereupon the motor 80 isy automatically stopped.

, The controller system for the'inotor .w80 comprises a circuit 83k includingu a battery 84 or other suitable source'offelectriccur- A rent. The circuit 83 isQso arranged. in connectioirwith its. cooperating Acontrolling parts thatl upon the closingY ofthe f circuit the motor 80 is set in voperation in such'rdirection as-to throw the clutchesf55 and 62 out of operation and to set the brake 76.

This Yswitch comprisesl 'two contacts SiS-.86 (see Fig. 2) spacedapart land coni nected with the circuitwires 183. The space between the, c ontactspS-S is adapted to be bridged by Ya rmovable switch member 87 connectelwth thegyoke 71,'V theoperatng i scribed.

, f The circuit 83 is also provided with a plurality of other. switch devices` S8 connected. in parallel across the circuit.. Eachv of these switches comprises .contact'mem-l. bers 89f9() connected with the circuit wires,VV adaptedto be moved into vcontact with `each other for closing the switch A'by an upwardV movement of a pin 9.1' (see Fig. 6)., The pins 91are adapted to ybe moved upward forclosingfthe switches` by.mea ns of arms 92 pivotally mounted upon the fr amel() carrying vat their ends: transversely-extend.- ing rollers 93 which during the normal op= eration of the press are( supported ,by` the webs 40.-,41 in conjunction with suitable springs94. y. As will :bereadily understood, in case Veither of. the ywebs 407-41; should break during; the operation Aof the-press at high speed, the corresponding y,roller 93 wouldmove down suddenly againstthe. ac.-

tionof the spring .94, servingtopush upward thepin 9,1 .of theadjacent .switch 88 servingtoclose the circuit S3 for throwing the motorSO into operation for stopping the press. yIncase the -web should break during theoperation of the press atlow speed, the closing ofthe switches 88 would haveno effect, inasmuch as the lcircuit wouldalready be broken vbetween the contacts 85%.-86, as above described.
